// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
|
||||
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
|
||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|

// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.

// About Desktop OpenGL function loaders:
|

// Modern desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.

// Helper libraries are often used for this purpose! Here we are supporting a few common ones (gl3w, glew, glad).

|

|

// About GLSL version:
|

// The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
|

// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
